Rewrite 24 * x in a different way, using the commutative property of multiplication. Note that x represents a real number.

Ivan

The communicative property means that multiplied numbers can be multiplied in any order.

3*2*4 is the same as 2*4*3. The answer will be the same.

So (24 * x) is the same as (x * 24).

Hope this helps! :)

the length of a rectangle is 2ft more than twice the width. The area is 180 ft^2. find the length and width of the rectangle

Mariana [72]

Answer:

Area = length * width

112 = (2w+2)*w

112 = 2w^2 + 2w

0 =2w^2 + 2w - 112

0 = w^2 + w - 56

0 = ( w + 8 )( w - 7 )

w+8=0 results in negative measures

w-7=0 --> w = 7

width is 7

length is 16

Write the following polar equation in Cartesian coordinates:

maks197457 [2]

Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)

Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))

Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
